Increasing the digital repository of DNA barcoding sequences of sand flies (Psychodidae: Phlebotominae) [PDF]

, 2019
Sand f ly identification is complex because it depends on the expertise of the taxonomist. The females show subtle morphological differences and the occurrence of the species complexes are usual in this taxon.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

The Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Intraspecific variability among Lannea species reveals promising morphotypes and ethnotypes in the semi-arid savannas of Burkina Faso (West Africa)

Journal of Agriculture and Food Research
Lannea species are among the fruit trees with high socio-economic importance in West Africa yet their intraspecific variability remains poorly studied, despite being essential for selection and domestication.

Illumina based whole mitochondrial genome of Junonia iphita reveals minor intraspecific variation

Genomics Data, 2015
In the present study, the near complete mitochondrial genome (mitogenome) of Junonia iphita (Lepidoptera: Nymphalidae: Nymphalinae) was determined to be 14,892 bp. The gene order and orientation are identical to those in other butterfly species.

On the use of ultraviolet photography and ultraviolet wing patterns in butterfly morphology and taxonomy [PDF]

, 2000
In a series of feeding experiments we found that, depending on the larval food plant species or part of food plant ingested, individuals of the blue butterfly Polyommatus icarus (Lycaenidae) exhibit broad variation of wing patterns in the ultraviolet (UV)

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Extending phylogenetic regression models for comparing within‐species patterns across the tree of life

Methods in Ecology and Evolution
Evolutionary biologists characterize macroevolutionary trends of phenotypic change across the tree of life using phylogenetic comparative methods. However, within‐species variation can complicate such investigations.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

The Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

Climate and soil explain contrasting intraspecific trait variability of widespread species over a large environmental gradient

Global Ecology and Conservation
Both climatic and edaphic conditions are currently undergoing significant changes on a global scale. Early studies have suggested that climate and soil together shape plant performance.
